Being a thrifty type, looking for tube headers at a reasonable price , just wasn't coming my way, got a couple of mid 50's fords that in need of better exhaust than a crossover pipe, I had bunch of SBC  headers, from my race cars, also I saw these imca modified headers that can be turned upside down. I cut and stretched the mid ports , welded the bolt holes, redrilled, they coming out nice. They clear everything, this can be done to almost any SBC header. It's more work, but worth it. Would make a great how to article for the rest of us,   tried to post pictures, but kept getting an error !
